With an ordinal scale, the measurements can be ranked in order, indicating the direction of the differences between them. This information is not provided by a nominal scale, which only identifies whether the measurements are the same or different, but does not indicate direction or magnitude. Option C is not entirely incorrect, but the size of the differences can only be estimated, and not measured precisely on an ordinal scale. Therefore, option B is the most appropriate answer.
